winbugsCARimmig.txt is a complete WinBUGS program, including the data, to estimate a conditional autoregressive (CAR) model of the tone of state immigration law, aggregated across 2005-2011.

stateImmig0511.dta provides the data for this model plus several additional variables.

immLaws0511.dta lists all immigrant laws identified by the National Conference of State Legislatures from 2005-2011. (Additional citation information is available in the paper.) Each law is coded for a variety of factors.
